Heads up: Not only is Amazon currently selling the upcoming 4-disc UP Blu-ray for $19.99, but if you pre-order it between now and November 10, they'll give you $10 off any other Disney BD. That means, for instance, you can get the 4-discers for UP and Monsters, Inc. for $32 and change.

Amazon says you have to enter DISNEYBD at checkout, but it automatically applied the discount on my order.
